HIGH VOLTAGE CIRCUIT BREAKER WITH CLOSING RESISTANCE INSERTION

摘要

P High-voltage circuit breaker with resistor insertion (3) on closing, characterized in that the resistor (3) is inserted by means of a fixed insertion electrode (13) cooperating with the end of the main contact mobile (16), the blowing nozzle (22) and the arcing contact (30-30A) of the mobile assembly being joined together and this sub-assembly being made mobile relative to the mobile assembly, such so that upon tripping, thanks to the inertia of said sub-assembly, the arcing contacts separate after a sufficient distance between the insertion electrode and the end of the movable main contact (16). /P
